Root Cause

A task is cancelled during asyncio.sleep(), which is a common cancellation point.

generic

中文

在asyncio.sleep()期间任务被取消，这是一个常见的取消点。

Workarounds

  1. 95% success 
    try: await asyncio.sleep(10) except asyncio.CancelledError: raise
  2. 80% success 
    await asyncio.shield(asyncio.sleep(10))

Dead Ends

Common approaches that don't work:

  1. 90% fail

    Blocks the event loop and defeats the purpose of asyncio.

  2. 70% fail

    May lead to resource leaks and inconsistent state.
